I have installed Ultimate SP1, v.688 on a Fujitsu Siemens PC and activated on line. I keep getting the message 'Your Windows licence will epire in 0 hours Back up your files and then install any edition of Windoes Vista' There is no error coden This appeared after SP1 was installed. Control panel-System shows 'Windows is activated' but it keeps shutting down at inapropriate times despite cahanging power settings to always on. I have tried changing the product key four times now in an attempt to force a phone activation code but it keeps activating itself whether I like it or not. this causes probs leaving slow apps running. This is VERY frustrating and i cant find any similar references on tech forums. Anyone any helpful ideas please as I dont want to have to reload all the apps and reformat if I can avoid it. PBS
